QUINCY, AND THREE-EIGHTHS TO GEORGE A. LUFKIN,

COP-SKEWER AND BOBBIN-FILLER.

Be it known that Quincy, county of Norfolk, chusetts, have invented acertain new an useful Improvement in Cop-Skewers and Bobbin-Fillers, ofwhich the following is a specification, reference being had'therein tothe accompanying drawings.

Cop skewersfor filling carriers for loom shuttles have been constructedwith a blade and with a hea dhaving annular ribs or rings whichare'adapted to enter grooves in springs carried by shuttles. Bobbinfillers have also been constructed with a base or head having annularribs or rings similar to those above described as used on pop skewersSometimes the head has been formed ensometimes ofmetal and wood. Theannular ribs however, have usually been formed of wire surrounding thehead. The head is usually the first part of the skewer or bobbin to wearout and as it is usually constructed the .head is made fast to the bladeso that when the head is worn out the skewer or the bobbin, as the casemay be, has to be thrown away. Moreover, the blade of the cop skewer isusually made differently from the blade of the bobbin and therefore thecop skewers: and bobbins are not interchangeable. Furthermore, as thebase of the cop skewer and bobbin has usually been constructed it isvery rigid and causes a great deal of wear and tear on the springjaws ofthe shuttle.

One object. of my inventionis to provide a cop skewer and bobbin fillerwith a head of simple and cheap construction so that they will be farless expensive to replace than those heretofore used.

'Another object is to makethe head detachable so that a new head may beplaced on an old blade.

1 Another object is toform the head in such manner that it will be moreor less yielding and of light weight and produce the least possible wearon the springs.

Another object is to provide the head with annular ribs integraltherewith.

Another object is to provide a blade of ,such form and character thatthe same device may be employed either as a cop skewer or as a bobbinfiller.

Application filed December 4, 1915. Serial No. 65,162.

The invention will be full; when taken in connection witl panyingdrawings and thef nov thereof will be pointed out and eea rlydefined'inthe claims atthe close of this speci fication. I,

In the drawings, Figure 1 is" a plan. new of one end portion of ashuttle containing a device embodying the longitudinal section of thepreferred form 'of device embodying the invention. Fig. 3 is an end viewof the device show-n in Fig. 2. Fig.4 is a longitudinal section of amodified form' of device embodying the .invention.

Fig. 5 is an-end'v-iew of the device shown in Fig. 4. Fig. 6 is alongitudinal section, and Fig. 7 is an end view of another modified formof the inventiornfl Referring now to the drawings, Figs. 1," 2, and 3, Ais the blade, and B the head of a device embodying the invention.

The blade A may be of any suitable mate rial, namely, wood, metal, orcomposition. The head B is formed of sheet metal all in one piece andmay or formed in any suitable way. It isa shell of annular form having asplitllengthwise of one side and is formed with a series of annularcorrugations forming ribs 2 which are adapted to engage the grooves inthe spring jaws end of the head B is formed with an inturned annularflange 5 which has a circular aperture of about the diameter of theblade A, but slightly less, the split extending through the flange, sohat'when theblade is to be inserted into the head B the flange 5 can besprung open sufficiently to admit the blade.

The flange is sufficiently resilient to grip the blade after the bladeis inserted. The flange 5 is preferably formed with an .inwardly turnedlip 6 to ing surface against the blade.

The top 7 of the head is of annular form having a central aperture 8-and has a tubuiar stem' 9 connecting with the rim of the apertures andextending back through the shell into the blade. Said tubular stem 9 isformed with a longitudinal split 10 so that invention. Fig. 2 is a bestamped out or bent 1 form a smooth bear- 3 of the shuttle 4. The lowerit can be sprung in to contract it to insert it into thetubularfinterior 11 of the blade. In

order to assemble the head with the blade the stem 9 will be I i asallowed by the slit already described, and forced into the passage inthe blade until the flange 5 reaches the 'lieadof the blade, then theflange 5 will be spread open as allowed by the sp'lit'l to enlarge theaperture sufiiciently to'allow the head of the tubular blade blade toenter it, then the entire shell will be pushed in until thecap portion 7comes against the end of the blade as shown in Fig. 2. The tendency ofthe split stem 9 to spring back to its normal diameter will cause bladeis formed with a shoulder 12 on the securely in place.

periphery against which the inturned will bear to hold the head B moreThe lip 6 then will snap into place behind the shoulder 12 when the headis forced onto already described. If theblade A is made of metal thehead B can be still more firmly secured, if desired, by soldering"the-.1ip 6 to the blade but preferably it outer lip 6 sired.

In the modification, shown in Figs. 4; and

I 5, the head B isformedwith a tubular stem the shell is formed integralwith the stem in Y a similar manner to that shown in Fig. 2

. having the ribs 2, flange 5, and lip 6, the u "ofhthe blade and holdthe 6, however bearing against the outer periphery of the stem '13instead of directly against the blade A. he contractile tendency of thehead causes'it to hugthe outside head and blade together, although, ifdesired, the stem may contracted by squeezing it,

the blade in the manner with a longitudinal the side thereof andextending is left un-- edge of the said flange to meet the saidcensoldered so that it may be detached if debe fastened to the .blade bysoldering or otherwise, if the blade is of metal.

In the modification shown in Figs. 6 and 7, the head B tegral and ofcase of the other forms shown.

lNh-at I claimis:

combination with a blade, part thereof and consisting of a hollow sheetmetal annular shell having an annular cap portion and being formed witha'longitudinal slit extending through the side of the head and of thecap to meet the central aperture in the cap, said head being formed withannular ribs pressed up out of the sheet metal and adapted to engagewith the jaws of. a shuttle.

2. A cop skewer or bobbin filler composed, of a single blank of sheetmetal shaped to form a hollow blade and a hollow head in- .tegraltherewith, said head being shaped at its outer end to form 'a flangeportion with said head being formed slit extending through from one acentral aperture,

tral aperture, said head being corrugated to form peripheral ribsadapted to engage with the jaws of the shuttle.

3. A cop skewer or bobbin filler having, in combination with a blade, ahead consisting of a hollow sheet metal annular shell having an annularcap portion integral with said head and being formed with a longitudinalslit extending through the side of the head and of the cap to meet thecentral aperture in the cap, saidhead being formed with annular ribspressed, up out of the sheet metal and adapted to engage with the jawsof a shuttle.

- In testimony whereof I aflix my. signature, in presence of a witness.
